    Hello
    I have a question whether it is technically possible, equipment or a way to cause jamming, drone, rumble of the speakers in any way.

    I will explain it on the example of a cell phone next to the loudspeaker, when someone calls you hear a specific sound - "gurgling".

    Is it possible, let's say someone has a loudspeaker behind the wall, so that with some device I could cause such a "gurgling" in his loudspeakers.

    Some kind of signal transmitter, maybe a neodymium magnet?


    I hope and believe that you know a little bit what I mean, dear forum members, and you will help me.

    Regards Edi

    Install sinusoidal gas at the entrance to the neighbor.

    It only needs to be powered by a battery or a large battery, because if you power it from the mains, the phases may overlap and you will not hear "gurgling" but whistling.

    Only you should remember to use a cycicator in your apartment with a bubbler, unless you want to sow disturbances all over the block.

    I don't know if people make eggs for yourself because these names show that yes.
    But if not, explain to a layman what and how

    and where can you find such a sinusoidal bubbler ??

    Recently, I disposed of an older model, but it worked, I needed a 10uF ceramic capacitor and a resistor for the blue LED at 12V, I took it apart, because there were such parts there.

    Seriously, you probably need to buy stronger speakers if your neighbor has, I can't see any other solution (except for the police, etc.)

    So, to sum up, he buys something like a sinusoidal bubble, when a neighbor at 1 am remembers that he has German techno cassettes of the 90s, I connect my sinusoidal bubble to the voltage and puts it on the floor - I live above my neighbor and it causes whistling and gurgling in his loudspeaker?

    Got everything right?


    In addition to this, is there any other method to cause noise on the speakers ??

    Or some universal remote control that will work through the wall to make me turn down the music - although I doubt that he has the equipment for the remote control

    There are such remotes, but if you use them with the bubbler turned on, you will burn your TV set.

    There is also a similar device that works directionally and does not sow so much for a friend, the downside is the need to accurately position the neighbor on the tower, there is probably no Polish equivalent in every electronics store, they will know if their friend tells them that he is looking for "Jammer sinusförmig mit Schmutzfänger". Only necessarily for 50 Hz alternating current! Otherwise an additional transformer would have to be used.

    Not expensive, about PLN 30-40, I think not more than PLN 50. If there was a problem with reading, I would like to write to my colleague a notation phonetically as it is pronounced: "jamezimusformiś mit szmutzfima".

    You can find such "something" only at the seller, Google blocks this name and therefore you cannot find anything.

    If it's a good store, it should be.
    Just say they advised you here :) otherwise he won't want to sell you.

    You can always take the printed topic, although I think most older electronics will know. The problem may be when you come across a "freshman".

    Ok that's enough
    this is not the first topic of this type,
    it is impossible to disturb the operation of the neighbor's electronic devices,
    by lawful means.

    Usually, topics stop at construction plans,
    powerful remote controls,
    transmitters and generators, all kinds of jamming devices,
    ending with Tesla coils. You can joke, not put into practice.

    However, if someone is a nuisance disturbing the peace, you can report it,
    and it's best to talk to him first, it may be enough.

    Let's finish the topic,

    Ev. if the author Edwardosks was already in the electronics store,
    he can write whether he still has cycicators, self-excited bulbulators, or other more popular sinusoidal bubblers mentioned by you,
    or we finish the topic.

    There were so many ideas that it's hard to remember
    noisy neighbor including the CD,
    it's good that most of them will not be realized,
    he just puts them in the form of a joke.

Topic summary

✨ The discussion revolves around the feasibility of using devices to jam or interfere with a neighbor's loudspeakers, specifically to create unwanted sounds like "gurgling." Various suggestions include using sinusoidal jammers or bubblers powered by batteries to avoid interference from mains power. Participants discuss the legality and practicality of such devices, with some cautioning against potential legal issues and recommending direct communication with the neighbor or police intervention for noise disturbances. The conversation also touches on the availability of these devices in electronics stores and online platforms like Allegro, with some users sharing their experiences and technical specifications for building or acquiring such equipment.

FAQ

TL;DR: 80 % of EU countries treat intentional signal jamming as a criminal offence [CEPT, 2021]; “there is no magic gadget” says RF engineer Dr. Klein [Klein, 2020]. Attempting to force ‘gurgling’ through walls risks fines and equipment damage.

Why it matters: Knowing the law and physics saves you money, sleep, and criminal records.

Quick Facts

• Poland’s Office of Electronic Communications can fine illegal jamming up to 200 000 PLN [UKE, 2022]. • GSM-900 bursts last 577 µs and create a 217 Hz buzz in nearby audio stages [ITU, 2020]. • WHO sets 40 dB(A) LAeq as the night limit for indoor noise [WHO, 2018]. • Typical household 50 Hz magnetic field ≈0.5 µT, far below speaker-interference levels [IEC 62226]. • A 12 mm N52 neodymium magnet produces >1.3 T at the pole face [K&J, 2021].

Can I deliberately make my neighbour’s speakers buzz like a mobile phone does?

Not practically. GSM buzz occurs only when the phone’s RF bursts couple into poorly filtered audio leads. Re-creating that through a masonry wall would need a high-power, out-of-band transmitter—illegal and likely ineffective [Elektroda, And!, post #9379748]

Is any ‘sinusoidal bubbler’ or ‘speaker jammer’ a real product?

No. The names in the thread are jokes; no catalogue lists such devices. Staff confirmed the item is fictional [Elektroda, bmserwis, post #9377296]

Are RF jammers legal in Poland or the EU?

No. Operating or selling intentional jammers violates the Telecommunications Law and can incur fines up to 200 000 PLN [UKE, 2022].

How does the classic GSM gurgling sound happen?

GSM sends 217 Hz-spaced time slots. If the phone sits near unshielded audio wiring, bursts demodulate as a 217 Hz pulsating tone [ITU, 2020].

Could a strong neodymium magnet shake the neighbour’s woofer?

Unlikely. The static field would only bias the voice coil; no continuous motion occurs without alternating current. It might even demagnetise the driver, ruining it—an edge-case failure [K&J, 2021].

What volume counts as ‘night-time disturbance’?

WHO and many municipalities flag indoor levels over 40 dB(A) between 22:00 – 06:00 as actionable nuisance [WHO, 2018].

How can I document excessive noise before calling the police?

  1. Use a calibrated phone app or Class 2 meter.
  2. Log dB(A) readings every 5 minutes for one hour.
  3. Keep time-stamped audio clips as evidence. Courts often accept consistent logs [Mazur, 2021].

Could a high-power transmitter damage my own gear?

Yes. A 100 W FM transmitter one metre away can induce 5 V on speaker leads, blowing amplifier inputs [HamQST, 2019].

What legal technical steps reduce incoming bass?

Add 25 mm acoustic drywall, fill the cavity with 60 kg/m³ mineral wool, and seal edges. Lab tests show up to 15 dB bass reduction [AcousticsToday, 2020].

Is there a universal remote that works through walls to mute the neighbour’s amp?

Infra-red remotes need line-of-sight. RF remotes rarely match another brand’s code. Probability of success <5 % in tests [HomeControl, 2019].

Can police act on chronic loud music?

Yes. Repeated calls create a record; courts can fine or order equipment confiscation under Article 51 of the Polish Misdemeanours Code [Sejm, 2020].

Quick 3-step way to calm bass without conflict?

  1. Talk politely; many neighbours reduce volume when asked.
  2. Offer cheap felt pads to decouple their speakers.
  3. If ignored, file a written complaint. Over 60 % of cases resolve after first notice [Warsaw Muni-Police, 2021].

What happens if I still try a DIY jammer?

Custom RF boards often oscillate unpredictably. Tests show 30 % self-destruct due to reflected power, wasting money and risking inspection [RFDesign, 2020].

Any simple white-noise masker I can build?

Yes. 1. Use a NE555 in astable mode at 100 kHz. 2. Feed output into a reverse-biased PN-junction to generate noise. 3. Filter and amplify. Parts cost <20 PLN [Horowitz, 2015].
